He might meet a mysterious old wizard. The wizard could be the one who brought Ash to the room, either for a purpose or by accident. The wizard could then guide Ash on a journey, or perhaps be an antagonist who has some dark plan for Ash.
Ash could meet a group of other people who are also trapped in the room. They could be from different backgrounds and have different skills. Together, they would have to work as a team to find a way out of the room, sharing their knowledge and resources.
He might meet Pikachu first. Since Pikachu is his closest and most loyal Pokemon friend, it would be likely that Pikachu would be by his side when he wakes up. Pikachu could be really confused at first but still show concern for Ash in his new state.
There's a high chance she'll meet Elena Gilbert. Since Elena is a central figure in The Vampire Diaries, she might offer some guidance or friendship to the girl. Also, the girl could run into Bonnie Bennett, the powerful witch. Bonnie could either protect her or be suspicious of her, depending on the circumstances. There are also the other vampires like Stefan Salvatore or Klaus Mikaelson who might cross paths with her for various reasons.
In the fanfiction, when Ash wakes up in the room, he might discover that he has new, unexpected powers. The room could be a sort of testing ground for him. He'll have to learn to control these powers while also dealing with the mysteries of the room, like hidden doors and cryptic messages on the walls.
It's possible that he meets Katara. Maybe she's also an early riser in this fanfic. They could then go for a walk together near the water, and Katara could show Aang some new waterbending moves she's been working on. This would be a great opportunity for them to have some one - on - one time and strengthen their friendship.
Ash might meet a strict teacher who has no idea about Pokémon at first but gradually becomes interested in them. He could also meet a rival in school who challenges him not only in academics but also in Pokémon battles.
He would probably be very confused at first. He'd look around, trying to figure out where he is and how he got there.
He might meet an old Pokémon expert who gives him tips on hatching the egg.
He might meet American wizards who are very different from his British friends. Maybe some tough - talking Aurors who have their own way of dealing with dark magic.
He might meet new Pokémon trainers in Alola. Maybe some young kids who are just starting their own Pokémon journey.
He might meet some of his old friends again, like Brock or Misty. Maybe they will join him on his new journey through the regions.
